Abstract
The utility model relates to a mechanical part, in particular to an electromotor belt pulley. The electromotor belt pulley comprises a pulley body. The pulley body is provided with a belt groove, a hole is formed in the center of the pulley body, and a bearing is arranged inside the hole in a sleeved mode. The electromotor belt pulley is characterized in that annular grooves are formed in the edges of the two sides of the pulley body, a transverse deep groove is formed in the bottom of the belt groove, ventilation holes are formed in the bottom of the transverse deep groove of the belt groove, communicated with the annular grooves and arranged in an inclined mode, the ventilation holes in the two sides and the transverse deep groove are connected to form an inclined hole, and an opening in the front surface of the pulley body is formed in the positive direction of an opening in the back surface of the pulley body. The electromotor belt pulley is simple in structure and reasonable in design, the deep groove is formed in the belt groove, the holes are communicated with the exterior of the pulley body, the two sides are communicated, the heat dissipation effect is good, water in the belt groove can be drained, and the phenomenon of idling caused by friction reduction due to the water can be avoided. In addition, the electromotor belt pulley is simple and practical.
Description
Technical field:
The utility model relates to a kind of component of machine, is specifically related to a kind of motor pulley.
Background technique:
Belt pulley, belongs to hub class part, and general relative size is larger, in manufacturing process generally with casting, be forged to master.What stock size was larger is designed to the method with casting, and material is all generally cast iron (castability is better), seldom uses cast steel (castability of steel is not good); Stock size is less, can be designed as forging, and material is steel.Belt pulley is mainly used in transmitting at a distance the occasion of power, for example output of miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machining equipment, textile manufacturing machine, package packing machine, lathe, forges bed, the transmission of some fraction horsepower motorcycle powers, the transmission of farm machinery power, air compressor, retarder, speed reducer, generator, Gins etc.
Model utility content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, and a kind of motor pulley of good heat dissipation effect is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of motor pulley, comprise wheel body, wheel body is provided with belt grooves, wheel body center is provided with hole, sheathed bearing in hole, it is characterized in that: described wheel body both sides of the edge are provided with annular groove, the bottom land of described belt grooves is provided with horizontal deep trouth, the horizontal deep trouth bottom land of described belt grooves is provided with air hole UNICOM annular groove, the oblique setting of described air hole, the air hole of both sides connects into an oblique hole with horizontal deep trouth, and the aperture in described wheel body front is positioned in the postive direction of position, aperture, the wheel body back side.
Described horizontal deep trouth and laterally the belt grooves bottom land between deep trouth are provided with anti-slip veins.
Described air hole and laterally deep trouth form a straight through hole.
The utility model is simple in structure, reasonable in design, is provided with deep trouth in belt grooves, outside hole UNICOM wheel body, and both sides communicate, good heat dissipation effect, and can get rid of the water in belt grooves, avoid reducing because water makes frictional force, occur the phenomenon of idle running, and oblique hole is convenient to wheel body when rotation, penetrates oblique hole by wind-force, moisture in cleaning eye or impurity, simple and practical.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: wheel body; 2: belt grooves; 3: hole; 4: bearing; 5: annular groove; 6: laterally deep trouth; 7: air hole.
Embodiment:
